Got 2 of these watches, 46mm for me the 42mm for my wife. The watch was very easy to setup with my Samsung Fold Z 3 for bluetooth. However the LTE part was a nightmare but I will put the blame on AT&T for that. I will go into detail on that part below. I upgraded from a Fitbit Versa 3 and I am happy that I did! I bought the LTE version but haven't committed to keeping the data plan, I usually have my phone on me but I can see where it would be nice when you don't want your phone on you such as the beach.Pro.Bluetooth easy to setupLots of awesome functionality, such as being able to silence your alarm on your watch. SMS pictures show up!The spin wheel on top is awesome for navigation.You can have it set up so you only get notifications on your watch when your phone isn't in use.Con'sBattery Life. I get a little over a day out of charge, I don't mind having to charge it every day but wish it had a physical connection, the wireless charging takes about 1.5-2 hrs to fully charge. My fitbit would last about 4 days for me and the magnetic physical charge would only take 30 min. Yes this watch does more but just wish it would charge faster or a bigger battery. I Like the sleep tracking so I don't like charging it while im in bed.Separate apps for the watch settings and for the physical tracking. Maybe some people like that but I am use to Fitbit's all in oneAll about LTELTE setup was a nightmare. I did it all through ATT, for those of you who don't know how it works your phone gets it's own phone number and your calls and messages get forward when your phone is out of range. This watch needs a eSIM card not a physical SIM. For ATT it will be about 30 bucks for a setup free and 10mo (13 with fees) as of 2022. eSIM card came fast in the mail (not sure why they just couldn't generate an email), next day after using ATT online order. When you set up your data plan you're just suppose to scan the QR code on the eSIM card and it all works. Mine didn't, had to call ATT support. After about 2 hours the kid on the other line got my account setup manually.The watch still didn't connect, ,got some sort of SDK error. So ATT put me in touch with a specialist who called me about 3 days later. He told me the SDK error should be fixed. and sure enough it was. Now we have to number sync with watch with the phone, got the code on the watch, no where to put the code in the phone, spent an hour trying to figure it out. Told me he would try to set it up again and try it the next day.The fixBefore he called, I figured it out. When I unpaired the watch from my phone it makes you set it up from scratch and since the ATT account was in my phone when I set the watch up it found my data plan and set it up. The button in the App to put the code in showed up, so this time when I numbered synced I had a place to put the code in and it worked.My wife's issueinstead of using the automation system my wife called ATT customer service, they sent her a physical sim instead of a eSIM. When she called ATT, she got someone who didn't know what to do. Called again the next day, the guy did get the account setup but then she got the SDK error that I got. The guy was telling her all the wrong stuff, I had to education the guy on what was wrong, his solution was that she could only set it up at the ATT store. We waited a couple of days and the SDK error fixed it self and she was able to number sync and it's been working since.Maybe this would have been less of a nightmare at an AT&T store but the only had one version of the watch for sale. Also between using Amazons CC and reward points the watch came out cheaper, worth the hassle in my book
